The invention discloses a photovoltaic panel support plate for quickly installing a photovoltaic panel. The photovoltaic panel support plate comprises multiple crossbeams and vertical beams which are perpendicularly connected. The crossbeams and the vertical beams are equidistantly distributed. The crossbeams are arranged on the upper end of the vertical beams. The photovoltaic panel support plate is characterized by comprising a fixed connecting hook and a flexible connecting hook of which the crossbeam hook heads are arranged in an opposite way. The distance of the external edge end surface of the two connecting hook heads is greater than the vertical internal edge distance of the back surface of the photovoltaic panel. The external edge distance of the two connecting hook heads is less than the vertical internal edge distance of the back surface of the photovoltaic panel. The upper end of the flexible connecting hook is the hook head. The upper and lower parts of the transverse extension end of the hook head are chamfered. When the photovoltaic panel support plate is used, the photovoltaic panel is hooked with the fixed connecting hook firstly, the other side of the photovoltaic panel is powerfully pressed and the two connecting hooks are enabled to hook the photovoltaic panel, and fixing connection of the photovoltaic panel can be completed by operating the locking mechanism; and the locking mechanism is loosened in disassembling, and the photovoltaic panel can be taken down by driving the lower end of the flexible connecting hook. Quick installation and quick disassembling of the photovoltaic panel can be realized so that operation is easy, and the worker can complete the work at the end part of the support plate.
